Explanation
The Timeout property on the HTTP Action in the Integration Procedure specifies how long to wait for a response from the external system before throwing an error. The Chain On Step checkbox on the HTTP Action in the Integration Procedure indicates that the next action should be executed only if the current action is successful. These two configurations should be used to implement the call to the external system given its known performance issues.

Explanation
The Invoke Mode Fire and Forget feature enables the OmniScript to invoke the Integration Procedure without waiting for a response. This is useful when the response is not needed for the user to proceed

Explanation
Versioning a FlexCard allows the developer to make changes to the FlexCard without affecting the existing instances of the FlexCard. The developer can choose to update all instances of the FlexCard with the new version or keep them as they are. This is useful when the changes are minor and do not affect the functionality or layout of the FlexCard. Cloning a FlexCard creates a copy of the FlexCard with a new name and ID. The developer can make changes to the cloned FlexCard without affecting the original FlexCard. This is useful when the changes are major and require a different configuration or design of the FlexCard1. In this case, since all instances of the FlexCard must be updated with the changes, versioning is the best course of action.

Explanation
A formula element allows the developer to define formulas using functions and operators to manipulate data in an OmniScript. The output of the formula element can be displayed to the user immediately in the current step using a display element. The CONTIF function counts how many times a value appears in a list1. A Calculation Action element executes a calculation procedure and returns the output as a JSON object. A Set Values element assigns values to variables or fields in an OmniScript. A Range element defines a range of values for a variable or field in an OmniScript1. Based on best practice, a formula element is the most suitable element to use the CONTIF function in this scenario.

Explanation
The merge code syntax for passing data from a DataRaptor Extract Action to an HTTP Action is
%DataRaptorName: NodeName%. In this case, it is %DRReadCase: CaseNumber%.
